ABSTRACT

Disclosed is a toy spinning top. The top includes a rotatable blade, a driving force generator coupled with the blade and generating a driving force to rotate the blade, and an attack ring detachably coupled with the blade to idly rotate against the blade. The toy top does not generate fragments when colliding with an adjacent top or other objects, and does not cause injury to a human body even if the toy top collides with the human body, so that the top can be used for safe play.

TECHNICAL FIELD

The present invention relates to a toy top. More particularly, the present invention relates to a toy top which may not generate fragments when colliding with an adjacent top or other objects, and may not cause injury to a human body even if the toy top collides with the human body, so that the top can be used for safe play.

BACKGROUND ART

A conical shape top having a symmetrical structure about a rotational axis is a toy that receives an external rotational force and spins about the rotational axis until the external rotational force is extinguished.

Due to rotational inertia, the top continuously spins without stopping. In other words, the top spins without stopping under the conservation of angular momentum.

An angular motion refers to a motion causing an object to rotate about one linear line while always maintaining the same distance with respect to one linear line. In other words, the angular motion signifies the momentum at a certain point, that is, the power efficiency at the certain point. In other words, a rotating object continuously performs the same rotational motion due to the inertia thereof in a space if external force is not applied to the object. Thus, the top rotates at the constant rotational speed about the same rotational axis if there is no external force applied to the top.

However, the top is stopped after the top is gradually slow down because the air resistance or the friction between a floor and the rotational axis serves as the external force.

In order to apply a rotational force to a top according to the related art, a conical-shape top may be thrown to the field by using a string wound around the body of the conical-shape top, or power may be supplied to the top by using the structure of a rack and a pinion. However, recently, there has been suggested a method of rotating a top by pulling a winder after fitting the top into the winder.

Meanwhile, as generally known to those skilled in the art, a typical top or a top injection-molded with synthetic resin may generate fragments upon the collision between the protrusion of the top and an adjacent top or another obj ect during the rotation of the top. In addition, when the top collides with a human body, accident may occur. In other words, since the top is manufactured without the consideration of the safety, the countermeasures therefor are required.

As shown in accompanying drawings, a top 100 according to the present embodiment includes a rotatable blade 110, a driving force generator 120 coupled with the blade 110 and generating power to rotate the blade 110, and an attack ring 140 detachably coupled with the blade 110 for the collision with an adjacent top (not shown) or other objects, and idly rotated against the blade 110.

The blade 110 constitutes a portion of an outer appearance of the top 100. The blade 100 includes a blade top 111 constituting an upper portion of the blade 100 and a blade bottom 112 detachably coupled with the blade top 111 at a lower region of the blade top 111.

The blade top 111 may be coupled with the blade bottom 112 through a rotary-pressing type scheme, but the present invention is not limited thereto. Accordingly, the blade top 111 may be screwed with the blade bottom 112 or hooked with the blade bottom 112.

A recess part 111 a recessed downward is formed on a top surface of the blade top 111, and a design cover 115 is partially received in the recess part 111 a.

A hook 115 a is provided on the design cover 115 so that the hook 115 a is locked with a hole 111 b formed through the top surface of the blade top 111. The top surface of the design cover 115 has a pattern 115 b to provide esthetics to the top 100. The present invention is not limited thereto, but may include various patterns.

As shown in FIG. 8, a plurality of magnet receiving parts 116 are formed in the rear surface of the design cover 115, and first magnets 117 are received in the magnet receiving parts 116.

As described above, if the first magnet 117 is coupled with the design cover 115, the game can be performed by using the magnetic polarity of the first magnet 117. As shown in FIG. 8, the top 110 according to the present embodiment, which has been assembled by receiving the first magnets 117 in the design cover 115, is rotated and then an additional magnet of the user is disposed near the design cover. If the first magnet 117 has the same polarity as that of the additional magnet of the user, the top 100 is pushed to a desirable position through repulsive force. If the first magnet 117 has the polarity opposite to that of the additional magnet, the top 100 is pulled toward the additional magnet of the user through the attractive force.

Such a play scheme based on the first magnet 117 allows the top 110 to continuously spin without reducing the rotational force of the top 110 when comparing with a scheme of changing the rotational direction of the top 110 by directly touching the top 100.

The driving force generator 120 generates power used to rotate the blade 10, and rotates together with the blade 110 in operation. The driving force generator 120 includes a shaft bush 121 coupled with the blade 110, a pinion 122 coupled with the shaft bush 121, a shaft 123 fitted into the pinion 122, a pair of gear housings 124 coupled with each other while surrounding the pinion 122 and the shaft 123 and provided at one side thereof with wire entrance ports 124 a through which a rack-type winder (not shown) geared with the pinion 122 to rotate the pinion 122 is introduced and withdrawn, an apex holder 126 having an lower end portion coupled with an apex 125, and a handle 127 coupling the gear housings 124 with the apex holder 126.

An upper portion of the shaft bush 121 has a non-circular sectional surface so that the shaft bush 121 is idly rotated with respect to the blade 110 when the shaft bush 121 is coupled with the blade 110, and a non-circular hole 112 a corresponding to the upper portion of the shaft bush 121 is formed on the blade bottom 112.

The pinion 122 is rotated by the rack-type winder (not shown) to rotate the shaft 123. In order to smoothly rotate the shaft 123, bearings 128 a and 128 b are coupled with both sides of the shaft 123.

A plurality of wire entrance ports 124 a, through the rack-type winder (not shown) is input or output, are provided at positions different from each other, so that the rotation of the top 100 is performed clockwise or counterclockwise by the driving force generator 120.

In other words, as shown in FIGS. 5 to 7, one pair of the gear housings 124 surrounding the pinion 122 and the shaft 124 are provided, and each gear housing 124 has two wire entrance ports 124 a.

Therefore, as shown in FIG. 7, if one pair of the gear housings 124 have been assembled, four wire entrance ports 124 a are formed in total. The wire entrance ports 124 a are used to select the rotational direction of the top 100. In detail, if a user pulls the rack-type winder after the rack-type winder used to rotate the pinion 122 is inserted into the winder entrance port 124 a having the desirable rotation direction, the top 100 can be rotated in the desirable rotation direction.

An end portion of the apex 125 makes contact with the grounding surface to serve as the center of the rotation. According to the present embodiment, the apex 125 serves as an offensive apex 125 having a truncated con shape, and the shaft 125 a of the apex 125 is press-fitted into a shaft hole 126 a.

However, the scope of the present invention is not limited thereto, but the apex 125 may include a hemi-spherical shape defensive apex 125 as shown in FIG. 10.

The handle 127 connects the gear housings 124 with the apex holder 126. A plurality of handle rings 128 are additionally coupled with an outer portion of the handle 127, so that the handle rings 129 can idly rotate with respect to the handle 127. According to the present embodiment, the handle rings 129 are coupled with upper and lower portions of the handle 127 along the length of the handle 127, respectively.

When the handle rings 129 are fitted around the handle 127, the handle rings 129 can rotate together with the handle 127. However, if a predetermined assembling tolerance is provided between the handle rings 129 and the handle 127, the handle rings 129 can idly rotate about the handle 127. Therefore, when the toy top 100 is rotated, even if a user grips the handle rings 29, the top 100 can continue to rotate. When the additional handle rings 129 are provided as described above, the user can grip the top 100, which is spinning, to move the position of the top 100 more advantageously.

According to another embodiment, as shown in FIG. 9, a second magnet 130 may be additionally coupled between the handle rings 129. Similarly to the first magnet 117, the second magnet 130 enables a play based on magnetic force (polarities).

Meanwhile, although a unit serving as the attack ring 140 is integrally formed with a top according to the related art, the attack ring 140 is coupled between the blade top 111 and the blade bottom 112 with a predetermined assembling tolerance according to the present embodiment. Accordingly, the attack ring 140 is not rotated with the blade 110 even if the blade 110 is rotated.

When the user plays a top spinning game while attacking another top, the attack ring 140 is coupled between the blade top 111 and the blade bottom 112 with a predetermined assembling tolerance.

As described above, if the attack ring 140 is individually manufactured without being integrally manufactured, and if the attack ring 140 is assembled between the blade top 111 and the blade bottom 112 with a predetermined assembling tolerance, the attack ring 140 can freely rotate independently form the blade 110.

Therefore, when the top 100 collides with an adjacent top or another object when rotating, the attack ring 140 can rotate in a direction opposite to the rotational direction of the top 100. Accordingly, the top 10 can be prevented from being fragmented or causing injury to a human body due to the collision with the adjacent top or the another object.

Even if the attack ring 140 collides with the adjacent top, since the tops 100 can absorb the collision between the tops 100, the rotational force of the tops 100 is not cancelled with each other, so that the time for the top spinning game can be increased.

A plurality of protrusion parts 141 are formed on the outer surface of the attack ring 140. According to the present embodiment, the protrusion parts 141 are arranged at an equal interval in a circumferential direction of the attack ring 140. However, the present invention is not limited to accompanying drawings.

According to the present embodiment, the top 100 further includes a weight disc 150 interposed between the blade top 111 and the blade bottom 112.

As shown in FIGS. 5 and 6, the weight disc 150 may include an offensive weight disc in which a plurality of grooves 150 a are formed radially inward thereof. In addition, the weight disc 150 may include a defensive weight disc in which the grooves 150 a are formed radially outward thereof. If necessary, regardless of the type of the weight disc 150, the blade top 111 is disassembled from the blade bottom 112 and then the weight disc 150 may be provided at an exact position between the blade top 111 and the blade bottom 112.

As described above, if a user enjoys top spinning game after the attack ring 140, which is manufactured separately from the top 100 and used according to requirements, and idly rotate with respect to the top 100, has been applied to the top 100, the top 100 is not fragmented when colliding with an adjacent top or another object. Even if the rotating top 100 collides with a human body, the top 100 does not cause injury to the user, so that the top 100 can be used for safe play.

Although the exemplary embodiments of the present invention have been described, it is understood that the present invention should not be limited to these exemplary embodiments but various changes and modifications can be made by one ordinary skilled in the art within the spirit and scope of the present invention as hereinafter claimed.
